A reoccurring frustration for philosophers of science: Many scientists know how to do science like people know how to ride a bike. When they reflect on the practice of science, they repeat platitudes about how science works. Those platitudes are often wrong, sometimes even about their own field

*sighs in philosopher of science*

Looking for confirmatory evidence is an entirely normal part of science. The primary problem here is the eugenics and the fascism, not the lies to children about "the scientific method."
One Bluesky account is quoting another. Inner post has a video of RFK Jr., some person I don't recognize (Tylenol and autism guy, maybe?), Marco Rubio (I think), and Trump. Post text: "RFK Jr on Tylenol and autism: 'It is not proof. We're doing the studies to make the proof." 

Outer post text: "We're doing studies to prove it (* not how studies work)"

I also particularly liked Gwendal Restoux's (INRAE) talk on genetic resources and potential strategies to make use thereof, and Anna Wolc's (Hyline, Iowa State) thorough update on the state of machine learning for poultry breeding and management.

And Tanmay Debnath (University of Edinburgh) talked about ML for phenotyping of the tibia.

Outwith of our project, there were more contributions about the keel, with genetic parameters from Pascal Duenk (Wageningen), and a poster on keel ossification from Lisa Hildebrand (FLI).

We had a pretty strong lineup from our department and the international FFAR keel bone project:

I talked about our genomic selection efforts, Khrystyna Kurta about genome-wide association and bone composition, and Moh Sallam about ML and new phenotypes for the keel.

Researcher day with the Beijer laboratories. Here: Elin Hernlund, my fellow Beijer researcher in the laboratory for animal science, talking about her models of shape and posture of domestic animals.

(It doesn't help that Prisma's import publications function has been broken since what, 2019? Please, pretty please with sugar on top, let us enter the publication list as a pdf like VR does.)

This year, the profile was cut down to a small text box, and we're back to list of 10 publications to be entered in Prisma. Gone are the ambitions to include more stuff than publications; it's now not even clear whether preprints count.

Last year's call introduced the academic profile for describing the merits of applicants in a broader way than before, including a wider understanding of an academic contribution than just a publication list. It came with a prescribed template, which was unfortunately quite awkward and bad.

The new format for the Formas Explore 2025 call--I say it's an improvement overall. Fewer boxes to fill in, and in the end a bit more space for implementation and references, so one doesn't have to hunt characters as much.

The new format of the academic profile is a step backwards, though.

On that note, it's time to seriously learn Bibtex, so I can let go of the Zotero plugin and rid myself of Microsoft Word.

Here's one powerful opening sentence:

"Under the banner of progress, products have been uncritically adopted or even imposed on users — in past centuries with tobacco and combustion engines, and in the 21st with social media."

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia:
doi.org/10.5281/zeno...

We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical
thinking, expertise, academic freedom, & scientific integrity.

Abstract: Under the banner of progress, products have been uncritically adopted or
even imposed on users — in past centuries with tobacco and combustion engines, and in
the 21st with social media. For these collective blunders, we now regret our involvement or
apathy as scientists, and society struggles to put the genie back in the bottle. Currently, we
are similarly entangled with artificial intelligence (AI) technology. For example, software updates are rolled out seamlessly and non-consensually, Microsoft Office is bundled with chatbots, and we, our students, and our employers have had no say, as it is not
considered a valid position to reject AI technologies in our teaching and research. This
is why in June 2025, we co-authored an Open Letter calling on our employers to reverse
and rethink their stance on uncritically adopting AI technologies. In this position piece,
we expound on why universities must take their role seriously toa) counter the technology
industry’s marketing, hype, and harm; and to b) safeguard higher education, critical
thinking, expertise, academic freedom, and scientific integrity. We include pointers to
relevant work to further inform our colleagues. Figure 1. A cartoon set theoretic view on various terms (see Table 1) used when discussing the superset AI
(black outline, hatched background): LLMs are in orange; ANNs are in magenta; generative models are
in blue; and finally, chatbots are in green. Where these intersect, the colours reflect that, e.g. generative adversarial network (GAN) and Boltzmann machine (BM) models are in the purple subset because they are
both generative and ANNs. In the case of proprietary closed source models, e.g. OpenAI’s ChatGPT and
Apple’s Siri, we cannot verify their implementation and so academics can only make educated guesses (cf.
Dingemanse 2025). Undefined terms used above: BERT (Devlin et al. 2019); AlexNet (Krizhevsky et al.
2017); A.L.I.C.E. (Wallace 2009); ELIZA (Weizenbaum 1966); Jabberwacky (Twist 2003); linear discriminant analysis (LDA); quadratic discriminant analysis (QDA). Table 1. Below some of the typical terminological disarray is untangled. Importantly, none of these terms
are orthogonal nor do they exclusively pick out the types of products we may wish to critique or proscribe. Protecting the Ecosystem of Human Knowledge: Five Principles

Sad but probably justified! :(

My next lecture in the course is QTL, so it's still there, but it has morphed, and a lot of it is about molecular trait mapping, eQTL and that stuff now.

Researchers should feel this often in contact with the literature. "There are tons of research about this ... but to different ends, and from other perspectives."

She illustrated this with an anecdote about getting to know roaches (the fishes), wanting to know about their behaviour and learning, and going to the library to find only books about catching and cooking fish.

Then philospher Jonna Bornemark talked about a model of knowledge (by her and Nicolaus Cusanus), going from sensations and drives through imagination, instrumental knowledge, intellectual critique, the absence of knowledge (the highest form of knowledge) and then back around again.

This course (Genome Analysis for MSc students) is always fun. When I came in to talk GWAS, my colleague had this on the board and a linkage map of the chicken Z chromosome on the projector. :)

It's funny how you're sometimes the most computer-minded among biologists and sometimes the most biology-brained among computer people. I feel I might have been on the latter pole yesterday, trying to drag the discussion down into the mud of application.
